Photonuclear and Two-photon Interactions at High-Energy Nuclear Colliders

Understand

Ultra-peripheral collisions of heavy ions and protons are the energy frontier for electromagnetic interactions.

• Both photonuclear and two-photon collisions are studied, at collision energies that are far higher than are available elsewhere.
• In this review, we will discuss physics topics that can be addressed with UPCs, including nuclear shadowing and nuclear structure and searches for beyond-standard-model physics.
